This is the sixth study in a project designed to find more effective and efficient ways of using micro-teaching and video recording in programs of vocational teacher education. In this field test of the feasibility and potential applicability of four related feedback and analysis techniques used in an inservice teacher education program for instructors in a technical institute, 28 instructors were assigned to four feedback and analysis groups: (1) self-review, (2)fellow instructor review, (3) student review, and (4) teacher-educator review. Also the study focused on three research questions which were concerned with differences in the effectiveness and feasibility of the feedback techniques and with differences in attitudes toward inservice experience. Analysis of the data revealed no statistically significant differences among the four variations on the instructors' teaching performance. All four techniques were found to be effective and feasible for inservice programs of teacher education in the technical institute setting. (Author/JS)
